Abstract: A transaction authentication system comprises a terminal (9, 20), a first memory (12, 18) and an IC card (1, 21, 51) which is detachably loaded into the terminal. The terminal supplies at least a transaction data which is related to a transaction and a designated storage region in a second memory (3, 4, 31, 32, 58, 59, 60) for storing the transaction data to the IC card when the IC card makes an access to a service via the terminal. A second processor (30, 54) of the IC card writes the transaction data received from the terminal in the designated storage region of the second memory and generates a verified data which is renewed every time the transaction data is written into the second memory. The verified data has a value in conformance with a predetermined generating algorithm and is stored in the second memory and also supplied to the terminal. A first processor (10, 11) of the terminal generates a transaction historical information which includes at least the designated storage region, the transaction data and the verified data and stores the transaction historical information in the first memory, so that a transaction is authenticatable from a correspondence of the verified data stored in the first memory and the verified data stored in the second memory.

Abstract: Part of a laser beam, which is generated by a laser tube (31) and reflected by a reflection surface (35a) of a high-reflectance mirror (35) to travel while diverging at the predetermined angle, is divided by a dividing mirror (37). The spectral band width of the divided laser beam is narrowed by an etalon (38, 39). The laser beam with the narrowed spectral band width is reflected by a high-reflectance return mirror (41), returned to the laser tube (31), and amplified in the laser tube (31). The laser beam with the narrowed spectral band width is amplified in substantially the same space within the laser tube (31) where the laser beam was generated.

IPC: B81C1/00
Filed: 1990-01-30
Abstract: A miniature transducer having an ultrathin tensioned silicon diaphragm so as to be responsive to extremely small changes in pressure. A silicon wafer is masked to define diaphragm areas, and etched to form a setback or capacitor gap a predefined depth. The mask is removed, and the entire silicon wafer is etched a second time to achieve the desired diaphragm thickness. The first and second etches are carried out independently, and thus the capacitor gap and diaphragm thickness can be independently formed. Mask and metallizing steps are carried out on glass wafers, and sandwiched around the processed semiconductor wafer, whereupon a large number of the miniature transducers are fabricated simultaneously. Unique patterning, etching and metallizing steps carried out on the sandwich structure allow a number of quadrature unit cells to be formed, thereby maximizing the area of the semiconductor and glass structures. By proper selection of materials, the diaphragm is tensioned during the fabrication of the transducer structures.

Abstract: An improved comprehensive system for definition of velocities of acoustic energy of sedimentary rocks is provided. First, geophysical exploration data available in the prior art is collected and organized to be defined as sequences and to define velocity behavior within sequences, and used to obtain consistently reasonable levels of accuracy of velocity distributions known by those skilled in the art. The present invention is particularly attentive to seismic sequence definition and to sequence compaction behavior. Secondly, in accordance with the present invention, means and methods not heretofore known in the art are used to sample well, seismic and other sources of data, on an individual basis, to define to what extent normal compaction behavior and velocities, as previously determined, may have been locally altered by other factors. Improved techniques to recognize several factors capable of causing abnormal post depositional behavior both at points of velocity control and elsewhere in areas of hydrocarbon prospecting interest, are intrinsic to the invention, and are important features thereof.

Abstract: The invention relates to a calender for making sealing gaskets, which has a motor-driven heating roll of large diameter mounted in non-displaceable bearings and an unheated pressing roll of smaller diameter which is driven by a separate motor and mounted in displaceable bearings against a pressing force. It is the object of the invention to provide a possibility of adjusting the circumferential speed of the rolls by permanent measurement of the gasket thickness as it is built up to obtain not only an exact synchronism of the roll circumferences but also a defined, controllable friction. The invention consists in that the two drive motors of the two rolls are controlled by a program-controlled processor, at whose one input is connected a travel sensor for the displacement of the axle or axle bearing of the pressing roll, at whose second input is connected a sensor for detecting the passing by of marks made on the heating roll or its drive shaft, at whose third input is connected a sensor for detecting the passing by of marks made on the pressing roll or its drive shaft, and at whose two outputs are connected control devices for the speed of the two motors for the roll drive.

Abstract: A value obtained by adding a back porch period following a vertical sync signal output from a CRT controller to the total number of horizontal display lines of a display resolution is set in a register (27). A counter (25) counts the value set in the register (27) in synchronism with a horizontal sync signal, and outputs a scanning start signal (SD) to a Y driver (31). With this operation, when a designated display resolution is lower than the physical resolution of an LCD, the scanning start signal is output before scanning of all the physical display lines of the LCD is completed. As a result, upper and lower non-display portions on the LCD display screen are simultaneously scanned.

Abstract: A method for leukocyte classification which relies basically upon flow cytometry that uses a first fluid that is hypotonic acidic fluorescent dye solution and a second fluid that is a solution that changes the osmolarity and pH of the first fluid is disclosed. In accordance with the method, a fluorescent dye that specifically stains the nuclei of damaged leukocyte cells is added to the first fluid and the resulting fluid is used in measurements. 
     The first fluid to be used in the method incorporates not only the first and second dyes but also the third dye and this insures that even leukocytes with damaged cell membrane can be distributed as entities distinct from other leukocyte types on a two-dimensional plot. And, hence, high precision of leukocyte classification is assured even in the case of assaying blood that contains damaged cells as a result of prolonged standing at room temperature after sampling.
